Hard-to-read content loses readers and can hurt engagement and SEO. The Readability Checker scores your text with Flesch Reading Ease and Flesch-Kincaid Grade Level so you can simplify for a broad audience, meet grade-level targets, or improve engagement and SEO.

What is Readability Checker?

The Readability Checker evaluates text using two standard metrics: Flesch Reading Ease (0–100; higher = easier) and Flesch-Kincaid Grade Level (U.S. school grade needed to understand the text). You paste your text; the tool computes scores from sentence length and word length (syllables). Analysis runs in your browser—your text is never sent to any server. Use it to simplify content for a broad audience, meet grade-level targets, or improve engagement and SEO.

Key Features

  • Flesch Reading Ease — A score from 0–100. Higher = easier to read. 60–70 is plain English. Below 30 is difficult.
  • Flesch-Kincaid Grade Level — The U.S. school grade level needed to understand the text. Grade 8 = 8th grade reading level.
  • SEO — Readable content keeps users on the page longer and can improve engagement signals that search engines consider.
  • Input — Paste your text. The tool computes scores from sentence length and word length (syllables).
  • Privacy — No. Analysis runs in your browser. Your text is never sent to any server.
  • No account — Use as often as you need without sign-up.

How to Use the Readability Checker

  1. Open the Readability Checker tool.
  2. Paste your article or page text. View Flesch Reading Ease and Flesch-Kincaid Grade Level.
  3. Simplify sentences or vocabulary if scores are too difficult. Use the "Use tool" button on the docs page if you are reading this from the documentation.

Real Use Cases

  • Broad audience — Target 60–70 Flesch (plain English) or grade 8–10. Rewrite until scores match. Use with Word Counter and Keyword Density Analyzer.
  • SEO and engagement — Readable content keeps users on the page longer. Check readability before publish. Pair with Meta Tag Checker for full on-page.
  • Academic or technical — Lower readability may be intentional. Use the tool to document grade level for consistency.
  • Client or team — Show readability targets. Use report as reference for style guides.
  • Before/after — Compare scores before and after editing. Track improvement.
  • Accessibility — Aim for lower grade level when content must be widely accessible.

Why Use the Readability Checker Instead of Alternatives?

  • vs. Keyword Density Analyzer — Keyword Density Analyzer focuses on keyword distribution. This tool focuses on sentence and word complexity. Use both for content quality.
  • vs. Word Counter — Word Counter counts words and characters. This tool adds readability scores. Use for audience fit.
  • vs. Meta Tag Checker — Meta Tag Checker checks meta and structure. This tool checks body readability. Use both for full SEO.
  • vs. Manual — No need to count syllables and sentences. Paste, get scores, adjust.

Benefits for SEOs, Content Writers, and Editors

  • SEOs — Improve engagement signals. Align content with target audience reading level.
  • Content writers — Hit readability targets. Simplify without losing meaning.
  • Editors — Standardize grade level. Use Flesch scores in style guides.

Common Mistakes

  • Ignoring context — Technical or legal content may need lower readability. Use scores as a guide, not a strict rule.
  • Only checking once — Re-check after edits. Scores change with sentence length and word choice.
  • Expecting keyword analysis — This tool is readability only. For keywords use Keyword Density Analyzer.
  • Forgetting to copy — The result is not saved. Copy or screenshot if needed.
